MartnySinclair: There is nothing wrong for being patriotic and in fact a good quality. But you are also a very sensible one as well!!!
This current shamble in LHR is a combination of years of lack of investments and certainly contingency planning by the airport operator and the dominant flag carrier and possibly the UK government as well. Same story with other forms of transport in the UK as I have had a taste of that in the past.
The main thing now is to get all the miserble travellers to their destinations ASAP in time for this coming festive season and to work out a future plan in order to reduce these crippling chaos in the future when snow hit hard at Heathrow again. Any improvement is a step forward!
